A study on the effective extraction layer of overburden fracture zone in goaf based on key layer theory

The effective extraction layer of the overburden fracture zone in goaf is the basis for arranging high-level extraction boreholes to treat adjacent layers and gas in goaf. Based on the key layer theory, a mathematical model for the effective extraction layer in fracture zones is established, and the...
